SPINNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 645,915, dated March 20, 1900. Appiicaionnea October 23,1899. Serin No. 734,426. (No model.)

which the yarn-carrier or bobbin' is rotated,I

the latter having contained bearings and a loose whirl to be engaged by the yarn-carrier.

While in my present invention the whirl and yarn-carrier are practically one in operation, yet they are readily separable when it is necessary to piece up or doff.

Various features of my invention will be hereinafter described in detail, and particularly pointed out in the claims.

Figure l, in side elevation, represents spin# ning apparatus embodying myinvention, the yarn-carrier being omitted. Fig. 2 is a vertical sectional view thereof with theyarncarrier in position, and Fig. 3 is a detached` Sectional view of the whirl.

Referring to the drawings, an .upright cylindrical metallic standard A is iixed at its lower end in a base or holder B, having an externally-threaded Shank B to receive a suitable nut B2, by which the holder is secured to the usual rail. The longitudinal bore h in the holder, in which the standard A is fixed, is oounterbored at b', Fig. 2, and at the .top of the holder a chamber b2 is formed concentric with said counterbore and surrounded by an upturned eXteriorly-threaded flange b3. A support or step d, annularly shouldered at d', is iitted to slide in the chamber b2 on the standard A, the shank d2 of said support entering the counterbore b' and being sustained by a spiral spring s therein, said spring tending to always lift the support.

The whirl f is shown as anannulus having an external band-receiving groove f', an annular shoulder f2 at its top, and a downwardly-tapered opening f3, which opening is preferably dared at its upper end, as at f4.

The whirl loosely surrounds the standard A and is held from removal by the overhanging ring-like stop 7L of a guard h, interiorly threaded at its lower end to engage the flange bsaud overhanging the shoulder d of the yielding support d to retain the latter in place. Between the base and the stop h a connecting-neck 71X is interiorly concaved, as at h2, Fig. 2, and shaped to correspond substantially to the periphery of the Whirl to support the latter against the pull of the driving-band BX, Fig. 1, and out of contact'with the standard A when the yarn-carrier is removed. The whirl may be of metal or wood, as desired, and if made of wood it can be treated with an antifriction compound.

The yarn-carrier C is preferably made of Wood or other suitable fibrous material having an eXteriorly-tapered base c and bearing portions c' c2 at or near the ends of the yarncarrier to embrace the standard with a running flt. Between the bearings the yarn-oarrier is bored, as at c3, to prevent engagement with the standard, and the bearing-sections are preferably impregnated with an antifriction compound.

When the yarn-carrier is to be applied, it is slipped over the standard H and through the stop-ring h', the tapering base c of the yarn-carrier entering the annular whirl f and passing therethrough into engagement with the support d, which yields as the whirl and yarn-carrier are pressed downward until the latter passes sufficiently through the whirl to firmly engage therewith by frictional contact. The operative then releases the yarncarrier, permitting the spring s to act to bring the parts into proper operative position, as shown in Fig. 2.

It will be understood that when the yarncarrier enters the whirl it moves it downward and laterally from the position shown in Fig. l into the position shown in Fig. 2, thereby centering the whirl relatively to the standard and interposing a bearing, as c', between the standard and whirl and withwhich bearing the whirl rotates.

The whirl and yarn-carrier are yieldingly maintained in vertical position when in operation by the support or step d, the tapering base of the yarn-carrier being made long enough to pass through and project slightly below the bottom of the whirl.

When it is necessary to stop the rotation of the yarn-carrier either to piece up or doif, the operative draws the yarn-carrier upward until the top of the whirl is engaged by the overhanging stop h', so that the tapering base o of the yarn-carrier can then be drawn out of the annular whirl and off from the standard A.

My invention is not restricted to the precise construction or arrangement of parts herein shown, as the same may be varied or rearranged without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim, and desire to secu re by Letters Patent, is-

l. A rotatable yarn-carrier, a fixed axial support therefor, and a loose annular whirl adapted to frictionally engage and rotate the yarn-carrier, said whirl having its internal bore of suiicient diameter to receive the end of the yarn-carrier.

2. A rotatable yarn-carrier having an externally-tapered base, a fixed axial standard therefor, and a whirl loosely surrounding the standard and adapted to be entered and frictionally engaged by the tapered base of the yarn-carrier, the said base at such time preventing engagement of the whirl and the standard.

3. In spinning apparatus, a xed upright standard, a removable yarn-carrier having contained bearings to fit the standard, a whirl through which the base of the yarncarrier is adapted to pass and frictionally engage, and a yielding support for the end of the yarn-carrier projecting below the whirl.

4. A standard, a yarn-carrier adapted to be rotated thereon, an annular whirl to engage and drive the yarn-carrier, and means to yieldingly sustain said yarn-carrier and whirl vertically.

5. A fixed standard, a whirl loose upon it, and a removable yarn-carrier adapted to e11- gage and center the whirl and to provide a bearing therefor in contact with the standard.

6. A11 upright metal standard, a Wooden yarn-carrier having contained bearing portions adapted to engage the standard with a running iit, and means to yieldingly support the yarn-carrier in vertical position on the standard.

'7. Arotatable yarn-carrier having a taperr ing base, a fixed axial support therefor, a whirl having a tapering bore to receive the base of the yarn-carrier, and a support to peripherally sustain the whirl when disengaged from the yarn-carrier.

8. An upright, fixed standard, an annular whirl loose thereon, an exterior, eccentrically-located support therefor, and a removable yarn-carrier rotatable upon the standard and adapted to engage and support the whirl, and to center it upon the standard.

9. In spinning apparatus, an upright standard, a chambered holder therefor adapted to be attached to a supporting-rail, a spring-controlled step for the yarn-carrier in said chamber, an annular whirl loose on the standard, and a stop for the whirl.

IO. In spinning apparatus, an upright xed standard, a whirl loose thereupon, a removable yarn-carrier adapted to be rotated upon the standard when in frictional engagement with the whirl, and a ring-like stop for the whirl through which the yarn-carrier passes, said yarn-carrier being interposed between the whirl and the standard.

1l. In spinning' apparatus, a fixed upright standard, a whirl loosely surrounding it, and a guard for the whirl, having an overhanging stop portion and a support to sustain the whirl peripherally against the pull of the driving-band.

l2. In spinning apparatus, an upright standard, a whirl loosely surrounding it and having an annularly-shouldered top, and a guard for the Whirl, having an overhanging ring-like stop to engage the shouldered top of the whirl when lifted, and an external support to pcripherally sustain the whirl at times.

13. 'A fixed standard and its holder, combined with a spring-controlled step supported independently of the standard and which yields as the yarn-carrier is applied to the standard.

14. A fixed standard, its holder, a loose whirl, and a stop to coperate with the upper end of said whirl, combined with a springcontrolled step adapted to yield under the action of the lower end of the yarn-carrier as it is being forced onto the said whirl, the return of said stop into its normal position moving said yarn-carrier and whirl into operative position.

l5. A fixed standard, its holder counterbored at its upper end, a step loosely snrrounding the standard and located in the counterbored portion of the holder, and a yielding support for the step, independent of the standard.

1G. A fixed standard, a holder for its lower end, said holder having a rising neck provided with a laterally-extended stop surrounding the said standard, combined with a loose Whirl surrounding said standard and retained between the said stop and holder.

17. An annular whirl, a fixed standard, surrounded loosely by said whirl, combined with a yarn-carrier having a central bore or chamber surrounding said standard, the lower end of said yarncarrier being shaped substantially as described to be forced into and entirely through the said whirl, between the latter and the standard, to thereby cause said yarn-carrier and whirl to adhere and insure the rotation of the former by a band on the latter.

18. A iixed standard and a holder for it, combined with a non-metallic yarn-carrier surrounding and running directly on the standard at its upper and lower ends, a loose ring- IOO IIO
